Keeping the Cost of Tailings Storage From Becoming

2020-4-8  The tailings are usually hauled and/or conveyed to the deposition area and compacted to form a dry stack. “All of these processes have advantages and disadvantages,” Burkhalter said. “The capital costs associated with thickened, paste and filtered tailings are much higher than conventional slurry tailings. Water recovery is the key.

Economic Potential for reprocessing Copper Mine Tailings

2016-7-31  Four copper mine tailings in Chile were investigated for their elemental and mineral composition, in order to evaluate the potential for economic reprocessing. The sample material, taken for processing had Cu-contents between 0.1 and 0.5 %. Copper was abundant in various primary (mostly chalcopyrite) and secondary (cuprite, atacamite, b

Mining Waste Management: Reprocessing Tailings

Mining waste management: The importance of Tailings Reprocessing. Tons of excavated material are extracted every day in mines around the world but only a small percentage contains the wanted mineral. This process is called ore grade. Have you ever wondered where the leftover material goes once the valuable part has been picked out? The answer is as simple as alarming.

2020-4-30  Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. (make-up water costs). This liberation is dependent on the physical properties of the

What are alternative uses for tailings? Weir Group

By utilising tailings as a material with value, as opposed to waste, customers are able to extract ‘treasure from trash’, reducing the need for a whole new mine site to mine those minerals. In the face of new challenges and a changing mining landscape, the collapse of tailings dams demonstrates that safety cannot be compromised and new

Costmine Industry Standard for Mining Cost

Backed by an extensive and unparalleled in-house cost database with 35+ years of history, this is a unique combination in the industry that allows us to conduct prefeasibility-level cost estimates and project evaluations with unprecedented reliability and efficiency, allowing you to make better mine project investment decisions.

Operating Cost for Miners SRK Consulting

Mine cost estimation may be done at many levels. At first it may be a simple “back of the envelope” estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them.
